What is the Best Smoke Detector?

Every year in the United States, nearly 3,000 people die in residential fires. Although accidental fires can occur at any time, one of the best ways to keep you and your family safe is to install a smoke detector in every room of your home.

Once properly installed and maintained, today’s advanced smoke detectors are on guard 24 hours a day, constantly scanning for signs of fire, smoke, or particulates in the air that can signal a problem. By maintaining constant vigilance, this simple and economical device can save your life, and help protect your valuable property.

The Technology Behind Smoke Detectors

Today’s advanced models rely on three different core technologies to alert to the presence of smoke and/or fire. Many smoke detectors available now feature one or more kinds of sensors, doubling your protection. Regardless of the type of sensor or programming, all smoke detectors have two basic parts: a sensor, and an alert (usually a combination of a loud noise and a flashing light).

Some smoke detectors are powered by a battery in the unit, while others are directly connected to the house current. Regardless of what kind of smoke detector you choose, it is essential that you test your smoke detector once a year, replacing batteries or the unit if necessary.

Modern smoke detectors feature different sensor technology, including:

  • Ionization – By taking advantage of electromagnetic properties on the molecular scale, an ionization sensor is able to quickly and accurately respond to very small amounts of smoke. Many times, fast flaming fires like those that occur in the kitchen, or the ignition of paper or gasoline, produce very little smoke at the outset. An ionization sensor can quickly respond to these types of fires.
  • Photoelectric – The tried and true technology of a photoelectric sensor uses two tiny beams of light, cross-set at a 90-degree angle. When smoke or particulate matter interfere with the light beam, the sensor is triggered and the alarm sounds. Photoelectric sensors are particularly accurate at detecting slow-burning, smoldering fires, which can be the result of an electrical short or other household accident.
  • Dual Sensor – A combination of both a photoelectric sensor as well as an ionization sensor, these smoke detectors offer maximum vigilance in case of a fire or smoke.

How to Choose the Right Detector for You

Any smoke detector is better than none, as these invaluable devices can save your life. However, it is worth considering that ionization sensing smoke detectors often trigger accidentally when used in kitchens if they respond to burned food in the oven or hot grease used when frying. Photoelectric sensors are better at sensing fires that occur when people are asleep, the light sensor being particularly effective at sensing smoke from slow-burning, smoldering fires. Dual sensor smoke detectors offer the most comprehensive coverage, but it is important to know that some models will appear to be functioning normally even if one of their sensors has malfunctioned.

To help you choose the right smoke detector for you, below are reviews of three of the most popular models on sale today:

“Just minutes after I installed the Nest Protect, the carbon monoxide alarm started going off.
